Abstract
The utility model relates to a dual-filtering infusion device. A drainage needle is connected with a filter through a liquid pipe, and the filter is provided with the liquid in an infusion bottle; the filter is connected with an air filter through the liquid pipe; one end of the self stopping gear of the filter is connected with a liquid bracket through the liquid pipe, and the other end is connected with a regulator through the liquid pipe. The dual-filtering infusion device adopts the double stage filtration to completely isolate the dust, the bacteria and the viruses in the air out of the infusion bottle to avoid the infusion infection and the infusion reaction. Simultaneously, the infusion self stopping gear avoids the blood returning phenomenon happening after the infusion is finished.
Description
This utility model relates to a kind of double filtering type transfusion device.
In the prior art, the transfusion device of using all is to filter by paper, but the filter opening hole is mostly about 0.46 micron, and the diameter of antibacterial and virus is at the 0.008-0.4 micron, so the paper filter can not filter out antibacterial and virus, therefore by the various viruses of infusing just along with infusion process enters human body, easily cause transfusion infection and infusion reaction to the patient; Transfusion can not stop automatically when medicine used up in the bottle in addition, caused the blood back phenomenon, and entourage's burden is very heavy.
The purpose of this utility model provides a kind of double filtering type transfusion device that adopts double-stage filtering.
The purpose of this utility model is achieved in that the double filtering type transfusion device, its fluid-directing needle (1) one side connects liquid bucket (3) through liquid pipe (2), its actuator (5) connects liquid filter (6), liquid filter (6) connects transfusion needle (7), fluid-directing needle also is connected with filter (8) through the liquid pipe, liquid in the infusion bottle is housed in the filter (8), and filter (8) links to each other with air filter (9) through the liquid pipe.
Compare with prior art, this utility model adopts double filter, wherein with in the filter 8 that fluid-directing needle and liquid pipe link to each other liquid in the infusion bottle is housed, dust in air, antibacterial and virus are isolated in outside the infusion bottle fully, have avoided transfusion to infect and infusion reaction; This utility model self-stopping gear of infusing in addition in addition, transfusion can stop automatically when a medicine used up in the bottle, had avoided blood back, had alleviated entourage's burden, especially to not allowing the especial patient occasion of being accompanied and attended to, was suitable for especially.
Be described in detail technical solution of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
As Fig. 1; one side of its fluid-directing needle 1 of double filtering type transfusion device connects liquid bucket 3 through liquid pipe 2; self-stopping gear 4 one ends link to each other with liquid bucket 3 through the liquid pipe; the other end links to each other with actuator 5 through the liquid pipe, and actuator 5 connects liquid filter 6, and the liquid filter links to each other with transfusion needle 7 again; fluid-directing needle 1 also is connected with filter 8 through the liquid pipe; liquid in the infusion bottle is housed in the filter 8, and filter 8 links to each other with air filter 9 through the liquid pipe, is provided with the automatic stop sheet in the self-stopping gear 4.
Claims (2)
1, a kind of double filtering type transfusion device, its fluid-directing needle (1) one side connects liquid bucket (3) through liquid pipe (2), its actuator (5) connects liquid filter (6), liquid filter (6) connects transfusion needle (7), it is characterized in that fluid-directing needle also is connected with filter (8) through the liquid pipe, liquid in the infusion bottle is housed in the filter (8), and filter (8) links to each other with air filter (9) through the liquid pipe.
2, double filtering type transfusion device according to claim 1; it is characterized in that it also includes self-stopping gear (4); one automatic stop sheet is arranged in the cavity of self-stopping gear (4), and self-stopping gear (4) one ends link to each other with liquid bucket (3) through the liquid pipe, and the other end links to each other with actuator (5) through the liquid pipe.
